## How To Find The Perimeter Of Equilateral Triangle?

Let's look at the geometric characteristics of an equilateral triangle. But first please review the definition of Perimeter Of Shapes (Two-Dimensional).
• An equilateral triangle has two unique features.
• The first unique feature - all three sides of the triangle are exactly the same length. In this example sides A are of equal length.
• The second unique feature of an equilateral triangle are the interior angles are exactly 60°. The sum of the interior angles is 180°.
• Special note, all sides of an Equilateral Triangle must be greater than zero.

Perimeter Of Equilateral Triangle
Perimeter = Side A + Side A + Side A =
Perimeter = A + A + A =
Perimeter = 3 × A =

ALTERNATIVE FORMULA TO COMPUTE PERIMETER:
Perimeter = Side A + Side B + Side C =
